Asynchronous loading

For large files, allow the first PDF pages to be loaded asynchronously, without having to load the whole document, which would normally take a very long time to load.

Reflow

Rearrange page content when the page size changes. This is useful for applications that have to prepare for the same layout being displayed on multiple devices. Create, render, release and access properties of reflow pages.

Content margins

Calculate PDF page margins:

by analyzing bounding box of all page contents

by detecting paths for background and images

BARCODES

Generate barcode bitmaps from a given string. Support for:

1D barcode: Code39, Code128, EAN8, UPCA, EAN13, ITF

2D barcode: PDF417, QR
